Aha. That explains it[1].

Well, one way is to go to a more complex regexp, with two halves, each
half being hardcoded for one type of quoting.
(?: # Match one attr name/value pair
\s+ # There needs to be at least
some whitespace
# before each attribute name.
[\w.:_-]+ # Attribute name
\s*=\s*
(?:
".+?" # "Attribute value"
|
'.+?' # 'Attribute value'
)
)* # Zero or more
